Compressed air energy storage (CAES) has been shown to have several distinct merits, including low cost, long lifespan, environmentally benign, and flexibility of scale and location. CAES technology works as follows: ambient air is compressed and stored using excess energy during off-peak hours; the stored air is later released to drive a turbine generator to produce electricity for peak hours. In this research project, we will develop a micro-scale CAES system using building foundation piles as the compressed air storage vessel and integrate the system with local solar panels/wind turbines. The pipe-pile-based micro-scale CAES (PPMS-CAES) concept is novel in that the pipe-pile foundations, which are commonly used as building foundations, are also actively used as air storage vessels for renewable energy storage. The goal of this project is to demonstrate the feasibility of the PPMS-CAES concept. The research student will assist in collecting data, and conducting energy analysis, thermodynamic analysis, and market analysis. Preferred background for this research position is as follows:

  • Have a good understanding of thermodynamics
  • Willing to learn about economic & market analysis
